SOLDEBING-IRON HEATER.

Application filed June 9,

To all whom it may concern.

Be it known that I, JosnrH NEEDHAM, a citizen of the United States, andresiding at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Soldering IronHeaters, of which the following is a specification, such as will enablethose skilled in the art to which it appertains to make and use thesame.

This invention relates to soldering iron heaters and particularly toapparatus of this class designed to be used in workshops or othermanufacturing institutions, and the object of the invention is toprovide a heater of the class and for the purpose specified in whichhigh pressure fuel gas is preferably employed as the heating medium; afurther object thereof being to so construct the heating apparatus as tomaintain an even degree of heat and to equally distribute the flamedischarged into the heater; and with these and other objects in view theinvention consists in an apparatus of the class and for the purposespecified which is simple in construction and operation and efficient inuse.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a front view of my improvedheater;

Fig. 2 a partial section on the line 2-2 of Fig. 1; r

Fig. 3 a partial section on the line 33 of Fig. 2; and,

Fig. 4 a partial section on the line 4 ff of F ig. 1 and indicating themethod of supporting soldering irons in connection with the heater.

In the practice of my invention I provide a base frame 5, which isapproximately rectangular in form and is provided in its corner portionswith angle iron legs 6. The inner face of the frame 5 is provided belowthe top portion thereof with inwardly directed flanges 7 which formtable or support for a heater or furnace body 8 com posed of separatetop and bottom parts 9 and 10 joined, as shown at 11.

My improved heater is of the general form and construction of a furnacecon structed on a comparatively small scale and Specification of LettersPatent.

Patented Nov.,15, 1921.. 1920. semen No. 387,604.

the separate parts 9 and 10 are preferably composed of fire-brick orsimilar material. The separate parts of the body 8 are molded separatelyto form when said parts are placed together, in the manner shown in theaccompanying drawing, a central heating or furnace chamber 12 whichopens outwardly through the front wall of the body 8 as shown at 13, andthis chamber or the top and bottom walls thereof are provided withinwardly directed and longitudinally arranged beaded portions 14 and 15,which divide the chamber 12 into two longitudinally arranged andapproximately cylindrical compartihents 16 and 17 placed incommunication as shown at 18.

The bottom part 10 of the body 8 is provided centrally of the chamber 12with a passage 19 which opens into the chamber 12, as clearly shown inFigs. 2, 3 and 4, and mounted in the passage 19 is a gas burner withwhich is connected a supply pipe 21 which passes throughone of the wallsof the frame 5 and to which is secured a suitable injector 22, part ofwhich is illustrated in Fig.1.

Formed in the part 10 of the body 8 are oppositely directed passages 23and 24, which communicate with the separate compartments 16 and 17, andalso with passages 25 and 26 formed in the periphery of the parts 9 and10 of the body 8, as clearly shown in Figs. 3 and 4. The passages 25 and26 meet centrally of the top portion of the part 9 of the body 8 andcommunicate with a backwardly directed passage 27 formed in said part 9.

The body 8, or the separateparts 9 and 10 thereof, is inclosed in asuitable casing 28 provided on its inner face with a non-heat conductingfacing 29, preferably composed of asbestos. The casing 28 is held inposition by front and back approximately arcshaped bands 30 and 31 intowhich the front and back edge portions of the casing 28 fit, as clearlyshown in Figs. 2 and 4C. The bands 30 and 31 pass into the top portionof the frame 5 and are secured thereto by screws 32 which securely holdthe casing 28 in position. The bands 30 and 31 are each composed ofL-shaped or approximately L- shaped strips, and one of the flanges atthe top of the strips 31 is enlarged as shown at 33 in Fig. 2sufficiently to cover the rear end portion of the passage 27. The band31 is also provided centrally of the top portion keep said furnacethereof with an upwardly directed tubular extension 84 which isapproximately elliptical in form and a flue pipe may, if desired, beconnected with said tubular extension to carry the gases of combustionto a suitable point at which they may be discharged. The casing 28 andfacing 29 thereof are also apertured as shown at 85 in line with thetubular extension 34 in order to place the passage 27 incommunicationtherewith.

The front of the frame 5 is provided with an approximately L-shapedextension 36, and the upwardly directed portion 37, or the top facethereof, is notched out as shown at 38. In the use of the apparatus andwhen suit, able soldering irons 89, two of which are indicated in dottedlines in Fig. 1, are placed in the heater, or the chamber 12 thereof,the shanks 10 of said soldering irons will rest in the notched portion38 of the extension 36.

The part 10 of the body 8 is recessed at the opposite sides of thecentral bead 15 thereof, and at the opposite sides of the centraltransverse plane of the chamber 12, as shown at 4:1 and 4:2. Therecesses 41 are in the compartment 16, while the recesses a2 are in thecompartment 17, and these recesses form in the compartments 16 and 17central ribs 13 and a l respectively. The ribs 4:3 and 14 form thesupports for the head end portions 45 of the soldering irons indicatedin dotted lines in Fig. 1, and the recesses 1-1 and 42 at the oppositesides of said ribs permit of the passage of the flame or products ofcombustion around the head portions 45 to thoroughly and evenly heatsaid head portions.

In the use of the device the gaseous mixture is introduced into theinjector 22 through the pipe 21 to the burner 20 and is ignite-cl withinthe chamber 12 and the flame from the burner 20 strikes the central.beaded portion 14 of the chamber 12 and directs the flame laterally asindicated by the arrows in Fig. 3, and the products of combustion aredischarged laterally through the passages 23 and 24 in the part 10 ofthe body 8 upwardly through the passages 25 and 26 into the passage 27at the top of the part 9 and out through the tubular extension 3%. Itwill also be apaarent that the flame within the separate compartments 16and 17 will pass through the recessed portions L1 and l2 around the headportions d5 of the soldering iron to heat the same.

By passing the products of combustion over the part 9 of the furnacebody 8, 1 prevent the chilling of said furnace body and body at an eventemperature at all times. The passages 25, 26 and 27 as well as thepassages 23 and 24: function as a jacket for the central portion of thefurnace body 8 for the chamber 12 of said body.

It will be apparent that soldering irons may be placed in and remo *edfrom the separate compartments 16 and 17 whenever desired, and with myimproved construction the head portions 45 of the soldering irons willbe equally and properly heated by reason of the method of distributingthe flame and the products of combustion around said head portions. itwill also be apparent that while I have described my improved heater orfurnace, as particularly designed for the purpose of heating solderingirons, I am not necessarily limited in this respect as the apparatus maybe used for heating various other articles, if desired, and changes inand modifications of the details of construction herein shown anddescribed may be made, within the scope of the appended claims, withoutdeparting from the spirit of my invention or sacrificing its advantages.
